Abstract

AbstractWe are looking into how well a copolymeric material made of poly (maleic acid–co‐4‐vinylpyridine) cross‐linked with divinylbenzene can separate L‐norepinephrine (L‐NEP) from (±)‐NEP. The initial step in this direction was the synthesis and subsequent analysis of L‐NEP‐maleimide chiral derivative. A 4‐vinylpyridine/divinylbenzene combination was copolymerized with the resultant chiral maleimide. After heating the polymer materials in a high‐alkaline environment to breakdown the connecting imide bonds, they were acidified in an HCl solution to eliminate the incorporated L‐NEP species. Fourier transform infrared spectroscopy (FTIR) and a scanning electron microscope were used to examine the imprinted L‐NEP‐imprinted materials. The manufactured L‐NEP‐imprinted materials exhibited selectivity characteristics that were over 11 times greater for L‐NEP than D‐norepinephrine. The highest capacity observed in Langmuir adsorption studies was 170 mg/g at a pH of 7. After optical separation using a column technique, it was determined that the enantiomeric excess levels of D‐norepinephrine and L‐NEP in the first feeding and subsequent recovery solutions were 95% and 81%, respectively.
